Questions & Step-by-Step Solutions

In a binary search implementation, what condition is checked to determine if the search should continue?
  • Step 1: Start with a sorted list and define the target value you want to find.
  • Step 2: Set two pointers, one at the beginning (left) and one at the end (right) of the list.
  • Step 3: Calculate the middle index by averaging the left and right pointers.
  • Step 4: Check if the value at the middle index is equal to the target value.
  • Step 5: If it is equal, the search is complete, and you have found the target.
  • Step 6: If the middle value is less than the target, move the left pointer to the middle index plus one (search in the right half).
  • Step 7: If the middle value is greater than the target, move the right pointer to the middle index minus one (search in the left half).
  • Step 8: Repeat steps 3 to 7 until the left pointer is greater than the right pointer or the target is found.
